If you're shopping for a used car in 2026, you've probably noticed prices aren't dropping as quickly as many experts predicted. After years of volatility following the pandemic, the used car market has entered a new phase: stable but stubbornly elevated prices, driven by an ongoing supply shortage that shows no signs of disappearing soon.
The fundamental reason for elevated used car prices is simple: there aren't enough of them to go around, particularly in the most popular age brackets.
During the COVID-19 pandemic, new car production plummeted. Factory shutdowns, combined with a global semiconductor shortage, meant roughly 2 million fewer new cars were registered between 2020 and 2022 compared to normal years. Those missing cars are now creating a significant gap in the used car market.
According to Auto Trader data, there are approximately 1.8 million fewer 3-5 year old cars available in 2026 compared to 2019. This age bracket is particularly popular with buyers looking for relatively modern vehicles at more affordable prices.
The UK used car market recorded approximately 7.8 million transactions in 2025, with forecasts suggesting this will rise to 8 million in 2026.
The shortage doesn't stop at newer used cars. Starting in 2026, the impact of reduced pandemic-era registrations is beginning to hit the 5-7 year old segment, which is expected to see a 17% year-on-year drop in available stock. This twin pressure is intensifying competition across the entire market.
Perhaps most striking is what's happening with older vehicles. Cars aged 10-15 years saw average prices rise by 8.5% year-on-year in December 2025, marking the ninth consecutive period of strong increases in this bracket. When newer used cars are scarce and expensive, demand naturally shifts to older, more affordable options.
Despite ongoing concerns about supply, overall used car prices showed remarkable stability in 2025. Auto Trader's Retail Price Index showed average used car prices fell by just 0.2% over the course of the year, with the average used car priced at £17,018 in December 2025.
The divergence in electric vehicle prices is noteworthy. While traditional petrol and diesel cars held their value well, used EVs faced pressure from aggressive manufacturer incentives on new electric models, particularly as carmakers pushed to meet Zero Emission Vehicle mandate targets.
Car insurance premiums have actually been falling, providing some relief for motorists. According to the Association of British Insurers (ABI), the average motor insurance premium dropped to £551 in Q3 2025, representing a 10% decrease compared to the same period in 2024.
This marks three consecutive quarters of falling premiums after the significant increases seen in 2023 and early 2024, when the average premium peaked above £600.
Insurance premiums have fallen 10% year-on-year, providing welcome relief after the significant increases of 2023-2024.
However, the relationship between used car values and insurance isn't straightforward. While lower premiums are welcome, several factors continue to put pressure on insurers:
Rising repair costs: Modern vehicles feature complex electronics, advanced sensors, and integrated systems that make repairs more specialised and expensive. Repair costs hit £1.9 billion in Q3 2025 alone.
Vehicle theft: The average theft claim increased by 3% to £11,800, with theft-related claims totalling £142 million in Q3 2025.
Record payouts: Insurers paid out £11.7 billion in car insurance claims during 2024, a record figure that continues to influence pricing.
If your car is now worth more than when you last insured it, your premium may not fall as much as the headline figures suggest. Always update your insurer if your car's value has changed significantly.
Industry forecasts suggest the used car market will remain relatively stable through 2026, with some potential for modest price adjustments:
Overall market: Used car transactions are expected to reach approximately 8 million, a 3% increase on 2025
Supply improvement: Some analysts predict supply will begin improving from mid-2026 as more vehicles return to market from extended finance contracts
Price pressure: As supply increases, there's potential for greater-than-usual price decreases, though not a market crash
Insurance premiums: Many experts believe premiums could continue to fall modestly if inflation stays low and repair capacity improves

With used car values in flux and insurance pricing constantly adjusting, comparing quotes regularly is more important than ever. Different insurers value vehicles differently and assess risk in their own ways, which can lead to significant price variations for the same cover.

The UK used car market in 2026 presents a mixed picture. While overall prices have stabilised after years of volatility, the underlying supply shortage continues to support values, particularly for desirable 3-5 year old vehicles and, increasingly, older budget-friendly options.
For buyers, patience and flexibility may be rewarded as supply gradually improves through the year. For those renewing insurance, the good news is that premiums have fallen significantly from their 2024 peaks, though individual circumstances will vary.
The key takeaway? Whether you're buying a car or insuring one, shopping around and comparing options has never been more important in this dynamic market.
